GATE.

Application filed September 16, 1920. Serial No. 410,685,

To all whom it may concern:

Be it known that l, FRANK S. RICHARD- SON, a citizen of the United States, residing at Willards, in the county of Wicomico and State of Maryland, have invented certain new and useful Improvements in a Gate, of which the following is a specification.

My invention relates to that class of automatic gates wherein the gate is operated by the wheels of a vehicle passing the same.

The principal object of the invention 16 to provide an apparatus of this nature wherein the vehicle will approach the gate and trip a mechanism which will open the gate in an opposite direction from the vehicle and when the vehicle has passed through the gate it will engage another trip mechanism which will close the gate.

Another object of the invention is to provide simple and eilicient means for keeping the trip mechanisms in a set position.

A still further object of the invention is to generally improve upon gates of this character-by providing a device which will be of extremely simple durable and inexpensive construction, one which is efiicient and reliable in operation and well adapted to the purpose for which it is designed.

l/Vith these and other objects in view this invention resides in certain novel features of construction and the combination and arrangement of parts as will be hereinafter fully described and claimed.

In the drawing Figure 1 is a fragmentary side elevation of my invention,

Figure 2 is a top plan view thereof,

Figure 3-is a fragmentary side elevation of the gate proper,

Figure 4 is a fragmentary side elevation of the post opposite the gate showing the latch mechanism used,

Figure 5 is a fragmentary end elevation of the gate showing the mechanism for hold-- ing same in an open position, and

Figure 6 is a side elevation of the mechanism used for resetting the trip mechanism.

Referring to the drawings by numerals thus it will be seen that 1 designates the fence post which is provided with the brackets 2 at its bottom and top portion. A plate of semi-arcuate construction 3 is fixedly mounted upon the lower end of the rod 4 which is rotatably mounted within the brackets 2. The upper end of the rod 4 is square in cross section and carries the link 5 so that upon rotation of this rod at the link 5 will also be rotated. It will be noted that the other end of the rod 4 is in engagement with the lug 6 on the gate so that when the link 5 is rotated by the rod 4 the top of the gate will be thrown outside of its center of gravity and thus swing to an open position in a manner well understood.

Spaced a desired distance from the gate post 1 is the stop post 8 against which the gate will abut when taking an open position. Situated adjacent the post 8 are a plurality of staples or any other suitable means 9 which hold the stop 10 in position. This stop 10 consists of a base portion 11 having an extension at one end from which extends the arm 12 parallel to the base portion 11. A lever 18 is mounted upon the end of the extension 12 as is clearly shown in Figure 2 of the drawing. Thus as the gate swings to an open position it will trip the lever 13 lifting the base portion 11 until the gate has abutted the post 8. The base portion 11 will then return the latch to the position shown in Figure 5 and prevent the gate from closing. Of course it will be understood that the weight of the base portion 11 will cause the above operation.

On each side of the gate there is situated beyond the post 8 a trip mechanism which consists of the lever 15 which is suitably mounted in the base plates 16. A bracket 17 having a pulley 18 thereon is situated beyond the lever 15 as is clearly shown in F igures 1 and 2 of the drawing and it will be noted that a cable has one end fixedly attached to the lever 15 and this cable 19 passes over the pulley 18 through the pulley 20 carried by the bracket 21 upon the opposite side of the gate and is fixedly attached to the arcuate plate 3 in any suitable manner. Thus it will be seen that as the vehicle comes toward the gate the wheel will trip the lever 15 thus pulling upon the cable 19 wnich in turn will pull the arcuate plate 3 in the opposite direction and open the gate in a manner already described. A. catch mechanism comprising the nose 22 mounted on the lever 23 having the right angular extension 24; is pivotally carr ed by the bracket 25. A similar mechanism is carried by the bracket 26. A link 2'? connects the extensions 2 as is clearly shown in Figure 6 of the drawing and one of the extensions 24 is provided with an elongated slot 27 so as to allow these extensions 24 to take the position shown in Figure 6 of the drawing which position will not allow the nose portion 22 to engage the lever 15. When the catch mechanism is in the position shown in Figure 1 of the drawing the lever 15 when pressed downwardly by the oil-coming vehicle will be engaged by the inner nose 22 and held in a trip position. Between the gate post 1 and tie latch post 30 l have disposed a trip lever 81 which is suitably mounted and to which is attached the cables 82 which have their outer ends attached to the lever 23 of the inner catch mechanism as clearly shown in Figure 1 of the drawings. It will also be noted that the lever 31 is of suflicient height so that the same will be abutted by the lower portion of the gate 7 as is clearly shown in figure 1 of he drawings.

Supposing that the gate has been opened and the vehicle has passed through the gate it will be seen that the wheel will have passed over the lever 31 thus releasing the nose 22 of the latch mechanism and allow the lever 15 to return to its vertical position. The gate however will not close because it is prevented by the stop mechanism 10. The vehicle now passes on to the opposite side of the gate and wheel thereof will press the lever 15 in the opposite direction which will also pull upon the cable 19 and therefore pull the plate 3 in the opposite direction and lift the end of the gate over the stop mechanism 1.0 and allow same to return to a closed position since the top of the gate will be outside of its center of gravity.

As the'gate closes the trip lever 31 will be slanting toward the open position of the gate and the gate therefor will abut this lever and throw same to the other side of the post 1 as will be readily understood from an inspection of Figure 1 of the drawing and the cable 32 will be pulled thus releasing the lever 15 from engagement with the nose 22 of the outside catch.

Upon the latch post 30 l have provided a latch mechanism which consists of the oppositely disposed lugs above which are pivotally mounted the wings 86 so that the pin 3'? upon the edge of the gate will abut the wings 36 when closing and it will be noted that this pin will prevent the gate from being opened except in the manner already described. when this end of the gate will be lifted over the pivot point of the wings 36.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the gate will be readily understood without a more extended explanation. As numerous changes in form, proportion, and in the minor details of construction may be resorted to without departing from the spirit of this invention, 1 do not wish to be limited to the construction herein shown and described other than as claimed.

Having thus described my invention what I claim as new is 1. In a device of the class described, the combination of a fence post, a gate hingedly carried by said fence post, trip means for opening and closing said gate, catch means for holding said trip means in an inoperative position, and a lever situated. below said gate when same is in a closed position so that it will be ahutted by said gate when same is closed so as to release said catch mechanism in the manner described.

2. In combination, a trip mechanism, a pair of levers pivotally mounted adjacent the trip mechanism so as to be situated on opposite sides thereof and each provided with an angular extension one of which is provided with a slot, and a link pivoted to the other angular extension and passing through the slot, said trip mechanism adapted to behold in an inoperative position by the noses of said levers and to be released therefrom upon actuation of either of said levers.

3. In combination, a fence post, a gate hingedly carried by said fence post, trip means for opening and closing said gate, catch means including a pair of lovers piv otally mounted on either side of said trip means and having noses for engaging the trip means whereby said means may be held in an inoperative position, each lever being provided with an angular extension, a link connecting said extensions, and means actuatable by said gate when same assumes a closed position for releasing said catch means from said trip means.

In testimony whereof I aflix my signature in presence of two witnesses.

FRANK SIEBERT RICHARDSON.
